Air cooler for Freon
Description
Application:
Air cooler for Freon is applicable to cold storage and food production plant; it is also widely used in food preservation, quick-freezing, refrigeration, cooler processing plant, as well as such industries like fishing, medicine, chemical engineering, chemical fertilizer, petroleum, coal, etc
Product features:
● Excellent chilling effect, low noise, long cooling range and stable operation
● Floating coil technique, safe and reliable structure and long service life
● Forward fin arrangement to ensure minor temperature difference between fin surface and inlet air and slower the frosting
● Copper pipe can be selected as heat exchange tube and aluminum sheet with hydrophilic film as the fins. Italian tube expanding equipment and technique are employed to ensure high heat transfer efficiency of evaporation coils
● Automatic welding process and equipment ensures product quality
● The housing can be made of galvanized sheet covered with electrostatic powder paint or stainless steel plate
● Stainless connectors and fasteners are adopted
● High-quality low-noise Germany axial flow fan is employed to ensure service life
● Electric heating defrosting or air defrosting method is adopted
● Versatile product type and extensive application
